Notes on the genus Rhaphium Meigen, 1803 (Diptera:Dolichopodidae

摘要

There are currently 26 Rhaphium species on the British List (Chandler, 1998), of which 21 have been reported in Yorkshire. The genus contains 4 Nationally Rare (NR) and 10 Nationally Scare (NS) species (Drake, 2018). These re-defined criteria equate to the 'Red Data Book' (RDB) statuses, and 'Nationally Notable' (Nb) in the most recent previous review (Falk & Crossley, 2005). Of the 21 Yorkshire species one is NR and eight are NS.
